What is the use of Einstein formula e= mc^2

1.	What is the use of Einstein formula e= mc^2
Answer» Explanation: The equation — E = mc2 — means "ENERGY equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same THING. If mass is somehow totally converted into energy, it also shows how much energy WOULD reside inside that mass: quite a LOT.
